I'll never understand how Tamba Hali didn't make the Pro Bowl this year. A monstrous pass-rusher, he registered 14.5 sacks. Capable of playing in any defense, Hali is going to make a ton of money this offseason.

Ray Edwards had a tremendous year, registering eight sacks and shutting down the run on his side. The question remains: How will he fare without the opposition keying in on Jared Allen and Kevin Williams?

One of the top young defensive free agents on the market, Charles Johnson became the fifth Panther ever to record double-digit sacks (12) in 2010. He was dominant from the left end position all year. Carolina cannot afford to let him go.

Jason Babin recorded 12.5 sacks in 2010. However, his previous high was five sacks back in 2006. Is he just a one-hit wonder?

Jamaal Anderson, DE/DT, Falcons. Age: 25. Signed with Colts (1 year)

Jamaal Anderson can't get to the quarterback, but is an excellent run defender. I'm ranking him relatively high because I think he could be a really good 5-technique in the 3-4.

Andre Carter, DE, Redskins. Age: 32. Signed with Patriots

One of the many reasons the Redskins sucked this season was because they couldn't get any pressure on the quarterback. Why couldn't they do so? Andre Carter's conversion from 4-3 end to 3-4 rush linebacker failed. Carter, who had 11 sacks in 2009, will thrive elsewhere.

Raheem Brock, DE, Seahawks. Age: 33. Re-signed with Seahawks

Raheem Brock was arrested for a DUI in early November. After that, he went on a tirade, recording eight sacks in the team's final seven games. Where did that come from? I'm not sure, but Brock turns 33 in June, so it's unlikely that he'll be able to continue this level of play for long.

Antwan Odom, DE, Bengals. Age: 29.
Antwan Odom is a great pass-rusher, but he can't stay healthy. If a team can bring him in for a cheap contract, that could be a great move.

Vernon Gholston, DE, Jets. Age: 25. Signed with Bears

Vernon Gholston was a huge bust for the Jets as the No. 6 overall pick in the 2008 NFL Draft. I'm listing him at 2.5 stars, however, for three reasons. First, Gholston is only 25, and has a ton of upside and athleticism. Second, I'd like to see what Gholston can do in a traditional 4-3. And third, defensive ends usually take a while to transition to the NFL. Granted, Gholston has shown nothing, but there's a slim chance he could be a very late bloomer. He's worth the risk.

Phillip Hunt, DE/OLB, CFL. Age: 23. Signed with Eagles

Phillip Hunt led the CFL in sacks with 16 last year. The last CFL pass-rusher to come into the NFL was Cameron Wake, but as far as this signing goes, the Eagles should be happy with half of Wake's production from Hunt.

Ray McDonald does a good job as San Francisco's third-down specialist on the defensive line. However, the 49ers will ideally find an every-down player to supplant the platoon of McDonald and Isaac Sopoaga.
